THUFUR MORPHOLOGY WITHIN THE PONOR DEPRESSION (STARA PLANINA, SERBIA)

Thufur (earth hummocks) are small periglacial landforms typical for subpolar latitudes, as well as for the high alpine areas at lower latitudes. Their presence in the mountains of the Balkan Peninsula was spotted during the mid-20th century. In this paper we analyze morphometry and morphology of thufur in the context of physio-geographical conditions for their formation. The main aims are to inventorize the thufur in the study area and to determine the physio-geographical factors which enabled their formation at non-zonal elevations. Statistical analysis was performed on the sample of 305 thufur mapped in the field, measuring their circumference, height, and delineating their areas. Classification of the results revealed morphological varieties in terms of horizontal and vertical development. The elevation of the sampling location Ponor is 1,410 m a.s.l., which is considerably lower than the zonal periglaciation in Serbia, at approx. 1,900 m. Therefore, the role of relief as a climate modifier is analyzed in the context of conditions for the azonal development of periglaciation process. Topographical conditions for thufur formation were analyzed through slope inclinations and vertical dissection, determined using the Digital Elevation Model over Europe with 25 m resolution

Risk education in Serbia

Natural disaster risk reduction can be achieved through vulnerability reduction, as well as through strengthening the resilience of the population. One of the segments leading to these aims is a proper risk education. It is the public (compulsory) education system that reaches the greatest number of participants and represents a good platform for the natural disaster knowledge transfer. Geography, as a complex subject that includes both natural and social components, is the most appropriate to transfer the knowledge necessary to improve the resilience. Research done in Serbia (detailed analyses of curricula, textbooks, teachers' role and pupils' knowledge) shows that children do learn about natural disasters but not in a way which provides usable knowledge

Public knowledge on karst and protected areas: A case study of Tara National Park, Serbia

The aim of this paper is to present the results of our research on the knowledge and awareness of visitors and residents about karst and protected areas (PAs). The research was carried out in the Tara National Park (NP) in western Serbia, which includes karst landscapes. By conducting surveys with visitors, local population, and National Park employees, as well as interviews with local key persons, NP key persons and external experts, we got a deeper understanding of the issues related to knowledge on karst and PAs. We also investigated whether local people or visitors knew the values of karst landscapes in general and how they were informed or learned about the Tara NP. In addition, we also analysed the content of these topics in school curricula and textbooks in Serbia. We concluded that the awareness about the researched topics is unsatisfactory at present thus it should be raised to a higher level, both in the case of local people and in the case of visitors. One of the most significant ways to improve the current level is through formal, non-formal, and informal education.The paper is a result of the project funded by the Research, Development and Innovation Office Hungary (NKFIH) K124497 and supported by the Ministry of Education, Science, and Technological Development, the Republic of Serbia. We thank all respondents who participated in the survey, as well as the Tara NP authorities (management) and Nikola Tomić for logistical support. Also we thank the reviewers for helping us to improve the paper

Stakeholders’ Attitudes toward Protected Areas: The Case of Tara National Park (Serbia)

This paper represents a case study examining attitudes of various stakeholders about Tara National Park (NP) (Serbia), identifying also the factors that shape these attitudes. The survey method was applied to a sample of 405 respondents (197 community members and 208 visitors). In addition, 15 interviews with specific key actors (NP executives and local key persons) were performed. The research confirmed the presence of different types of conflicts among stakeholders, mostly between the NP and the local population (primarily farmers) associated with land use in agriculture and the ban on the construction of facilities. The community recognizes tourism as the highest priority, unlike the NP leaders and visitors, who emphasize protection and conservation (especially biodiversity) as the primary goals of future NP development. The opinions of the local population are divided concerning support for the existence of the NP and the importance of it as a part of the national heritage. Most of them do not recognize the economic benefits resulting from the proclamation of the NP and do not see themselves as participants in the decision-making process. The findings also reveal that visitors strongly support tourism development and activities following the principles of nature protection. This category of respondents is only partly affected by the fact that this area has been declared a NP. The analysis shows that certain socioeconomic factors considerably influence the opinions of both community and visitors. Results suggest that future actions should be aimed at improving the coordination of various stakeholders, especially the NP and the community, through different social mobilization activities. Stimulating small businesses and providing incentives for agriculture and nature tourism development could be a useful step forward.This research has been supported by the National Research, Development and Innovation Office Hungary (NKFIH) K124497 project and by the Ministry of Education, Science and Technological Development of the Republic of Serbi

Karst Geoheritage of Tara National Park (Serbia) and Its Geotouristic Potential

By the example of Tara National Park (NP), we present how the geoheritage can and should be presented in a NP where the primary role is played by biology. Tara NP has a rich geoheritage, especially its karst phenomena, which include gorges (e.g. the 1000-m-deep Drina Gorge), plateaus with dolines, dry valleys, and uvalas as well as springs and travertines. In addition, ophiolites also enrich the geoheritage; hence, the area has a high geodiversity. Large reservoirs of the territory provide an opportunity to study the anthropogenic impact on hydrology and geomorphology. After presenting the geoheritage elements of the area, we examine the views and knowledge of local people and visitors about karst and geotourism with the help of a questionnaire survey. The results show that local residents support the further development of tourism, but geotourism is a rather new concept for them. On the contrary, tourists are more familiar with geotourism. Among the development perspectives, tourists support those that involve only minor environmental changes, that is in agreement with NP policy. Finally, we formulate some suggestions about geotourism development in the area. First, we outline some plans for new geo-educational trails and viewpoints. Second, we highlight the possibility to increase the geo-content of some already existing programs (e.g. boat tours). Third, we emphasize that geotourism of Tara should be connected to neighbouring areas. A new geopark is already under planning, which would include the area of Tara NP as well.Open access funding provided by Eötvös Loránd University.

The influence of chemical characteristics of precipitation on tree health in Banjica Forest (Belgrade, Serbia)

The most represented tree species in the Banjica Forest are Acer negundo, Quercus robur, Acer pseudoplatanus, Populus nigra, Fraxinus pennsylvanica, Fraxinus ornus and Robinia pseudoacacia. According to the ICP Forests combined assessment (degree of defoliation and decolorization), endangered species are Populus nigra (64.3% of heavily damaged trees), Quercus robur (45.5%), Fraxinus pennsylvanica (37.0%) and Acer negundo (26.6%), while the situation is much better for Acer pseudoplatanus and Fraxinus ornus. For Robinia pseudoacacia, 83% of trees are without decolorization, however, defoliation is established. In the period from April to October 2009, the average pH of rainwater was 5.46, and 5.18 in the period from November 2009 to March 2010. The concentration of SO42- in the period from April to October 2009 amounted to an average of 24.21 mg/l, and 28.87 mg/l in the period from November 2009 to March 2010. The concentration of SO42- and pH values is a possible explanation for the condition of the trees

Spatial distribution of specific runoff in Serbia based on rainfall-runoff relationship

One of the indicators of water potential and water resources is specific runoff. Specific runoff for the whole territory of Serbia was obtained using the exponential relation between depth of runoff Y (mm) and precipitation P (mm). This relation is obtained on the basis of the mean annual amount of precipitation and annual water discharge, namely the depth of the runoff for 69 basins for the period 1961–2010. Coefficient of determination (R²) of relation between the depth of runoff and precipitation is 0.72. The differences between measured and modeled values of specific runoff vary from basin to basin, but at the level of the whole Serbia it is 3.5%. More precisely, the measured specific runoff amounts 5.6 l/s/km2, and the modeled specific runoff is 5.7 l/s/km2. The verification was done by applying the model to 11 large river basins in Serbia. Spatial distribution of the modeled specific runoff is presented by a digital map of specific runoff with pixel resolution 100 × 100 m which enables the estimation of mean annual water discharge in any ungauged basin in Serbia

Vulnerability to natural disasters in Serbia: spatial and temporal comparison

The frequency of natural disasters and the extent of their consequences at a global level are constantly increasing. This trend is partially caused by increased population vulnerability, which implies the degree of population vulnerability due to high magnitude natural processes. This paper presents an analysis of vulnerability to natural disaster in Serbia in the second half of the twentieth and the early twenty-first century. Vulnerability changes were traced on the basis of demographic–economic indicators derived from statistical data for local government units (municipalities) provided by the Statistical Office of the Republic of Serbia. Calculations were performed in the geographical information system environment. The results of the study show that spatial and temporal vulnerability variations are causally correlated with changes in the selected components. Significant rise of vulnerability is related to urban areas, while lower values are characteristic for other areas of Serbia; this is primarily a consequence of different population density
